REFRIGERATING APPARATUS.

Application filed July 21,

This invention relates to refrigerators comprising a cabinet containing a cooling unit, and mechanical refrigerating apparatus for circulating refrigerant through the coola ing unit.

Hitherto, mechanical refrigerators in which the mechanical apparatus is contained within the refrigerating cabinet have been objectionable, in that the vibration produced lo by the moving parts, such as, for example, the compressor and driving motor, is transmitted directly to the cabinet, thereby amplifying the noise produced by the moving parts and at the same time causing the cabila net to creep or move from its original place. It is desirable to assemble the refrigerat ing apparatus within the cabinet at the ,fac-l tory, because the apparatus may be charged with the refrigerant medium and tested at the factory and then shipped to the consumer in condition for immediate operation; whereas, if the cabinet and apparatus are shipped separately, it' would be necessary to have them re-assembled and the apparatus re-cliarged and tested at their destination.

It is an object of this invention to provide a refrigerating cabinet in which the refrigerating machine may be assembled at the 3o factory and shipped with the cabinet as a unitary structure; and which can be adjusted when installed so that the vibration of the machine will not be transmitted directly to the cabinet. This object is accomplished by providing for the support of the refrigerating machine by the cabinet during 'shipment and by providing for the release of the inachine from the cabinet when installed while maintaining the connection between the ma' to chine and the cooling unit within the cooling chamber of the cabinet. n l

-Another object of this invention 1s to provide means for absorbing the vibration incident to the operation of a refrigerating compressor and motor.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of the present invention 1s clearly shown.

In the drawings:

broken away, of a refrigerator embodying this invention; and

`Fig. 2 is a fragmentary view on an enlarged scale, showing one of the supports .for the base of the refrigerator'.

rl`he refrigerator cabinet 10 includes an upper cooling Icompartment 11 and a lower compartment 12. Compartment 11 is cooled -by a suitable unit 13. A base 141 is provided in the machine compartment on which is mounted a refrigerant circulating unitwhich is herein shown for illustration as varompresso'r 15 driven by a motor 16. The compressed refrigerant gas is forced into the condenser 17 which may be mounted on the, base, if desired. The condensed refrigerant is forced into the evaporator 13 through a conduit- 18, and the expanded gaseous re frigerant is withdrawn therefrom through a conduit 19.

A bolt 2O` passes upwardly through an aperture 21 in the base 14 and through an aperture 22 provided in a horizontal supporting member 23. The member 23 is rigidly attached to a wall of the machine compartment. The bolt 20 is provided with a nut 24, and a cotter pin 25 is placed at the extremity of the bolt, to prevent the nut from being accidentally removed. A yieldable washer26, of rubber or similar mate rial, is interposed on the bolt between the base 14 and supporting member 23. Liliewise, a washer 27, preferably of felt, is interposed between the supporting member' and the nut 24.

Base 14 is provided with legs 28, each of which carries at its lower end a yieldable bumper or button 29, which may be of rubbei'. Similar bumpers or buttons 30 are also provided on the corner posts 31-of the cabinet. i l

Base 14@ is supported as shown in Fig. 2 at a plurality of places, preferably three. The

bolt 20 is of such a length that, when its nut is drawn up tightly, the base will be free from the floor 32 on which the refrigerator is placed, whereby the weight of the coinpressor and motor will be carried by the cabinet through the supporting members 23. ln this position, the cabinet and the assembled refrigerating apparatus are in condition for shipment as a unit; and, when the cabinet installed,- it is necessary only `to loosen the nuts until the base 14 rests on the ioor. Therefore, when the machine is operating, vibrations produced thereby will not be transmitted directly to the cabinet. The buttons 29 which support the base 14 tend to absorb the vibrations of the machine and to prevent. Vibration of the floorl The conduits 18 and 19 are provided with suitable bends or turns 33 and 34, respectively, which permit the raising and lower- 'ing of the compressor without disturbing the installed, it is but necessary to loosen the nuts, permitting the base to rest on the ioor, whereupon the refrigerator will be in condition for operation with the cabinet free from machine vibrations.

While. the form of embodiment ofi the present invention as herein disclosed, constitutes a preferred form, it is to be underv .stood that other forms might be adopted, all

coming'within the scope of the claims which follow.
